A spring is cut into two equal halves. How is spring constant of each half affected?

What is the unit of spring constant?

A spring has a mass m suspended from it. If the spring is cut in half and same mass is suspended, from one of the halves, will the frequency of vibration is changed ?

If a bar magnet is cut into two equal parts along the magnetic axis, then the magnetic moment becomes ?

A spring having a spring constant K is loaded with mass m. The spring is in two equal parts and one of them is loaded with the same mass. The new spring constant is

A block of mass 4 kg irioving horizontally on a frictionless table at speed 2ms^(-1) compresses a spring through a distance 10 cm before its speed is halved. Find the spring constant of the spring.

When a force of 0.1 N is applied a spring is stretched by 1.5 cm. The spring is cut into three parts and one part is stretched by 3 cm. The force required for this is

A reaction is second order with respect to a reactant. How is the rate of reaction affected if the concentration of the reactant is reduced to half?
